You don’t have to worry about having missed any of the free volumes either, each volume is unveiled on a separate day but the past volumes are also available (till the end of advent).

Note: Logos focuses on academic resources, I wouldn’t recommend these books to those beginning biblical studies (whether as a lay person or academically) with the exception of the Cornerstone Biblical Commentary.

Thus far the selection has included:

Cornerstone Biblical Commentary: 1 & 2 Timothy, Titus, Hebrews – Based on the New Living Translation. This is a good commentary to have.

N.T. Wright’s Scripture and the Authority of God. – Wright is one of the most controversial and well-known contemporary theologians.

Calvin’s Calvinism (2 Volumes) – John Calvin was one of the most famous theologians of the Protestant Reformation and his thought has been integral to much of present-day theology.

Tabletalk Magazine Bundle: Christian History (11 Issues) – Covers the second to twelfth centuries of Christian history.

Lexham Bible Dictionary – An awesome, constantly growing dictionary of the Bible. You don’t need to throw away those old, old print dictionaries you may have, but refer to the Lexham Bible Dictionary first to ensure you are learning about the latest studies. I find developments in understanding the Greek language and archaeological studies especially fascinating!

Crucial Questions Series (20 Volumes) by R.C. Sproul – I haven’t read these volumes myself, but Sproul has a solid reputation. His thought is from the Reformed school, which means an emphasis on predestination over free-will.

The Greek New Testament: SBL Edition – The Society for Biblical Languages (SBL) is well-known for its quality resources. If you want to read the New Testament in Greek, this can be a great Greek version to read.

Thanks Paul! The one warning I’d have about the bundles is that they are usually largely packed with older materials (19th century and before). Logos does a nice job with the intertextual linking and so on, but you can get many of these for free from various public domain archives such as CCEL or Project Gutenberg.
